8.5 Air Filter Maintenance
Contaminated air filters cause a reduction in engine
performance and increase fuel consumption with
more pollutants in the exhaust gas. Engines are less
likely to start readily with a contaminated air filter.
Carry out the following maintenance jobs regularly.
Before opening the air filter, close the choke to
prevent dirt entering the carburettor.
Turn the wing screw (31) at the air filter cover (11)
anti-clockwise.
Flip the top of the air filter cover forward and
remove.
Remove the fabric air filter (32).
Clean the area around the filter.
When using the equipment all day, clean the fabric
air filter daily. Under extremely dusty conditions,
clean the filter several times during the day as well.
Simply tapping the filter is the best cleaning method.
Never wash or clean the air filter with heigh
compressed air or by wetting it; never place in an
oil bath or into cleaning solution.
The air filter is blocked, if the engine speed
noticeably drops when the carburettor is correctly
adjusted. Under these circumstances, the filter needs
replacing (part no. 20 48 154).
Low engine speed due to a blocked air filter must
never be compensated by incorrect carburettor
adjustments. This would cause the engine to
overload, resulting in severe engine failure.
Engine failure caused by incorrect care is excluded
from our warranty.
Insert the new or cleaned fabric air filter into the
casing.
Position the air filter lid with the lower guiding pins
onto the housing and push into place.
Secure the filter cover by turning the wing screw
(31) clockwise.
8.6 Information about the silencer
Ensure the silencer is in perfect condition before
operating the machine. Never touch the silencer while
it is still hot.
Unsatisfactory engine performance, despite a clean
air filter and a correctly adjusted carburettor, may well
be due to a partially blocked or damaged silencer.
Please consult your specialist service centre.
8.7 Replacing the fuel filter
We recommend having the fuel filter (34) changed
annually by a specialised service centre.
A trained mechanic can carefully remove the fuel filter
via a wire loop through the fuel tank filler. Ensure that
the thicker part of the fuel hose on the tank wall is not
drawn into the fuel tank.
8.8 Shutdown and storage
Preferably, store the equipment in a dry and secure
place with a full fuel tank. Open flames or similar
must not be nearby. Prevent unauthorised use
particularly by children.
For stops longer than four weeks the following steps
should be carried out:
Empty and clean the fuel tank at a well-ventilated
location.
Start the engine with an empty fuel tank. Run the
engine until the carburettor is empty and the
engine stalls. Otherwise the carburettor nozzles
could become encrusted with residual fuel mixture
and make a subsequent start harder.
Clean the power tool well (particularly the air intake
openings, the cylinder fins, the air filter and the fuel
filler area).
Preferably, store the equipment in a dry and secure
place with a full fuel tank. Open flames or similar
must not be nearby. Prevent unauthorised access
particularly by children.
